Westerly Ventures replaced our entire roof and did an outstanding job. The crew was professional, showed up on time every day, and left the property spotless. Hand-nailed every shingle, you can tell the difference in quality. Highly recommend.

Had them pour a new driveway and patio. The finished product looks amazing. Neighbors keep stopping to ask who did the work. Fair pricing, great communication throughout, and they handled the permit process for us. Will definitely use again.

Our furnace died on the coldest week of the year. Westerly had a tech out the same day, diagnosed the issue, and had a new system installed within 48 hours. Professional, honest, and fast. These are the people you want working on your home.

Local Expertise

Roofing Services in Mercer Island

Mercer Island’s luxury homes demand top-tier roofing materials and installation. Wind exposure across the island, heavy tree canopy, and the premium property values here mean your roof needs to look as good as it performs. We’ve worked on many homes on the north and south ends of the island.

A damaged or aging roof doesn’t wait. Leaks cause mold, rot, and structural damage that gets more expensive every month you delay. Get a free inspection today.
